Concept:Inference-based reading: an inference is valid only if it is directly supported by the passage.
Explanation:The passage states that public transport is essential for reducing traffic congestion and pollution in cities.
So Inference I directly follows.
The passage also mentions challenges like overcrowding, delays, and poor maintenance, which discourage people from using public transport.
So Inference II directly follows.
The passage clearly says that governments are investing in modern infrastructure and digital ticketing systems.
Therefore, Inference III is false because it contradicts the passage.
Thus, only Inferences I and II hold true.
Answer:Option A: Both I and II follow.
